Abstract

Analysis of two extensive museum samples of Hipponoe gaudichaudi Audouin & Milne-Edwards indicates that this amphinomid polychaete broods its juveniles in intersegmental grooves. Juveniles undoubtedly migrate from the ventrum to the dorsum of juveniferous worms as they increase in size. Analysis of oocyte diameters and spermatocyte densities in relation to the number of body segments indicates that this species is a protandric hermaphrodite. The spermatozoa are primitive (Franzen, 1956).
